A fire-aspected Casket of Firedust Conversion inlaid with red jade in patterns of stylized flame, that turns firedust into stronger firedust.
As normal firedust.
If the gout of superheated flame fired by the firewand hits any non-living flammable material, that material automatically catches fire. If it hits a person, then the base damage is 18 dice of lethal.
